SDK: Problem from Max 8 to Max 9

[scorpion007]

How does the importing code process numerical data in these shaders?

Are the shaders your average .sl type of shaders?

Where does it get numbers anyway? Hard-coded arguments to the shader, or does it parse the shader source code and do something funky?

I'd need some more information to give further assistance.

I've attached the help file for MAXShade which explains how it works, and an example shader showing how the shader source code is adapted for MAXShade.

Basically when you load a shader, it gets parsed by the plugin, which then automatically builds a GUI for the shader using the #pragma statements.

I've spent a lot of time going through the code trying to find a reason for this problem, but when I realised that the Max 8 version works fine, I assumed that something has changed between 8 and 9 to break the parser.

ok, so if I understand this correctly, the problem is how maxshade parses the default values for the arguments? It doesn't treat the decimal point as a separator since your locale uses commas?

I can't say what the issue is without knowing how maxshade does this. Perhaps it relies on some max sdk feature that changed, but I wouldn't have any clue as to which one.

You might want to show the code for the argument parsing, or have another look at it.

I'm just assuming this has something to do with the locale settings, but I don't know for sure. It just seems really odd to me that Max 8 on the same computer has no problems.

I won't have time today (my daughters 5th birthday party, loads of kids to keep under control... :eek: ), but I'll upload the source code soon. It is open-source anyway...

OK, here is the original source code:
http://source.maxplugins.de/maxshade/maxshade.041204.zip

This is the Max 4 version, not the one I've already updated for Max 8/9
It just need the usual updates (there aren't many) for Max 8 and 9. I didn't upload the updated version in case I added the error (which is certainly possible!)

Cheers,

Hi Dave, im very interested in maxshade, but unfortunatly I dont have much knowledge in programming to update it for latest versions, could u be so kind to upload the max 8 version u updated, or at list explane how to do that?
Best regards

Hi Vladimir,

if I can find it, I'll upload it for you...

Here's the Max 8 version:

I think it works OK, but I haven't looked at it since October last year...

Thanks so mush Dave, I've been looking for it so long

Hi Dave, I was playing around with Maxshade, and i'ts fantastic, I was very impressed, that Vray actually rendered all shaders and even raytrace.sl worked well,
howerverI couldn't use renderman's ambient occlusion shader found here:

http://www.fundza.com/rman_shaders/ray/ambient_occlusion/occlude1.html

here is the code:

surface occlude1(float samples = 32){normal n = normalize(N), nf = faceforward(n, I);float hits = 0; gather("illuminance", P, nf, PI/2, samples, "distribution","cosine") { hits += 1; }/* find the average occlusion factor */float average = hits / samples; Ci = (1 - average) * Cs;Oi = 1;}
as far as I understood maxshade didn't understand gather() function,but it was not in the list of unsupported functions in maxshade,as I mentined before I'm not very goodin programming,do you have any idea how to use it,

thanks anyway

Vladimir

[maxplugins]

I think you'll find that Renderman functions added after the plugin was written just won't work. That's why it doesn't appear in the list of unsupported functions, because it didn't exist at the time the plugin was written...

Sorry I can't help more,

Dave

Hi, everyone

How could create a menu in 3dsMax menu bar with use C++ MAXSDK?

Thanks!

Using MAXScript is very easily!
But using MAXSDK ...
How write I don't know !
